The Austrian Audio OC7 small-diaphragm condenser microphone is designed to provide you with a stunningly true to life snapshot of any instrument you put in front of it. At the core of the the handmade OCC7 capsule (made in Vienna) is an impressively linear frequency response that's tailored to instruments with particularly active transients. The OC7's built in swivel mount makes setting up and adjusting your microphone a breeze, including a 220 degree range of roation. The OC7 also has a -10dB pad (the microphone is capable of >160dB) and two position low cut filter, which makes this condenser a must have for recording and live engineers, who require the utmost of versatility, durability and immaculate sound quality from their microphones. 

The OCC7 condenser capsule was developed in Vienna and is the heart of Austrian Audio’s small diaphragm microphone series. Inspired by the legendary CK1, the newly developed capsule takes on the heritage with the benefits of the classic and the demands of today. Shaped by the past, built for the future.

The OCC7 small-diaphragm capsule with true condenser technology, developed and built in Vienna, is the heart of the microphone. The capsule’s three micron thick gold-coated polyethylene naphthalate (pen) diaphragm is much more robust than conventional Mylar alternatives.

The OCC7 has an impressive linear frequency response. The capsule can withstand extremely high sound pressure levels. Combined with very low self-noise, this results in an impressive dynamic range. It always sounds natural and open, and even at extreme volumes it is neither harsh nor sharp. The mids and highs are always silky smooth and are not overemphasised.

Each capsule is hand-built in Vienna and measured and tuned in the in-house anechoic chamber.
